台湾中部造山带前缘呈现为一弧形逆冲构造体系。每个弧形带分别由不同尺度但各自独立的次级弧形构造所组成。而每一个弧形构造都有其各自独立的几何、运动和动力学特征 ,是典型的板块造山运动变形带前缘之褶皱逆冲带 ,但同时各个次级弧形构造间却又有自相似特性。台湾中部弧形系列构造带 ,由运动学看来 ,是从弧形顶部向西逆冲向两侧过渡到斜冲 ,到弧凹处的逆冲为止。每一个地震活动带与独立活动的弧形逆冲构造间可能有一定的对应关系存在。大地震发生在规模较大的弧形构造上 ,而中小地震则发生在规模较小的次级弧形构造上。在对台湾中部地区弧形逆冲体系的空间位置与地震活动间关系研究的基础上 ,文中归纳出中部弧型逆冲地震带的地震活动特征。
The leading edge of the orogenic belt in central Taiwan presents an arc-shaped thrust system. Each arc zone is composed of different scale but independent secondary arc structure. Each arc structure has its own independent geometric, kinematic and kinetic characteristics. It is a typical fold-thrust belt with the leading edge of deformation orogeny of plate tectonics. However, at the same time, each secondary arc structure has self-similarity characteristic. Central Taiwan arc series structure zone, from the kinematic point of view, is from the top of the arc to the west of the west thrust to the ramp on both sides of the ramp to the arc so far thrust. There may be some correspondence between each seismic activity zone and the arc-shaped thrust structure of independent activity. A large earthquake occurred in the larger arc structure, while small and medium earthquakes occurred in the smaller secondary arc structure. Based on the study of the relationship between the spatial location of arc-shaped thrust system and seismic activity in the central part of Taiwan, the seismic activity characteristics of the arc-shaped seismic zone in central China are summarized.
